Abstract (en)
[origin: EP3026835A1] The present invention relates to a method for detecting a jamming transmitter affecting a communication user equipment, said communication user equipment operating in a cellular network supporting uplink and downlink communication on one frequency band in a time-division manner, the cellular network comprising a plurality of base stations, including at least one active base station, which is the base station the communication user equipment is camping on, the method comprising the steps for the communication user equipment: - detecting that at least one downlink radio channel from the active base station is not decodable, - measuring signal levels received on said downlink radio channel for a plurality of time units, - analyzing said signal level measurements, - in case at least one time unit is detected with a signal level exceeding a predefined threshold, - detecting a jamming transmitter by verifying the condition that in a predefined amount of successive time units the pattern of a first time unit with signal level exceeding the predefined threshold directly followed by a second time unit with a signal level below the predefined threshold is not detected.
